BATTERY ELECTRODE-SUPPORT.

Specification of Letters Patent.

Application filed August 4, 1909 Serial No. 511,097.

. teries and particularly to that class employing zinc and copper platesas their positive and negativeelectrodes when used in connection with asuitable solution.

. The purpose of the invention is to provide a special and improved formof holding frame for supporting the said plate electrodes in theirproper position one with relation to the other Within a battery jar; todesign the frame in a simple, practical and inexpensive manner wherebythe said elements and especially the negative electrode plate will befirmly engaged around its edge portions leaving its two sides free forattack by the solution.

As designedthe frame is adapted to be supported from any one of severalstyles of covers and is further constructed to accommodate either asingle, or a series of negative plates as desired according to thecapacity of the battery to be produced.

Upon the accompanying sheet of drawings forming a part of thisspecification, similar characters of reference will be found todesignate like or corresponding parts through out the several figuresand of which,

Figure 1, shows a side elevation of our improved electrode supportingframe suspended from a battery cover and containing both a positive andnegative electrode. Fig. 2, is

a longitudinal, central, vertical sectional view through the electrodesand frame shown in Fig. 1. Fig. 8, shows a somewhat smaller and modifiedform of supporting frame designed to support a single negativeelectrode, and Fig. 4, shows a detached top edge plan view of the lowerportion of the frame with negative electrode supported therein.

Our improved supporting frame is formed of sheet metal and wire togetherwith suitable insulating blocks used intermediate of the positive andnegative electrodes 5 and 6, and in detail .comprises a hanger 7 that isformed of sheet metal having its longitudinal edge portions bent over toengage the edges of the plate.

sides of the edge portions of the negative plate 6 and serrated as at 8to insure a better attack of the solution -upon' the plates. 'lhishangeris of substantially a U shape and has its side portions disposed upwardat.

a right angle'to the intermediate bottom por-.

tion, which latter engages the bottom edge of the plate 6 while thesides engage the side An eye 9 is formed in the upper end of the sideportions of said hanger and may bejproduced by deflecting the upper endof the stock of the sides o ut-as shown in Fig. 2, or by securing aseparate piece of metal 10 thereto as shown in 1 and 4. A sheet metalchannel strip 11 is arranged across the top edge of the plate and isprovided at each end with a hole that registers with the eye 9 and thetwo serve to permit the ends 12 of the wire yoke 13 to be insertedtherethrough for the reception of nuts 14 and whereby the hanger issecurely Patented Feb.- 8, 1910.

drawn up against the several sideedges'of the negative plate or plates.

The yoke 13 is disposed crosswise of the top of the channel plate and isprovided with an eye 15 for the attachment of the bindin nut 16 for theconnection of the field wire 17 and is further provided with a looportion 18 to receive the inner reduced abutting faces of the insulatingblocks-1S) which rest upon the top and sides of the channel strip 13 andare secured together by means of a bolt 20. The outer faces of theseinsulating blocks are recessed to receive the shouldered portion ofthepositive lates 5 attached thereto by means of the b0 t 20 beforementioned. The hangers 21 by means of which theframe' and electrode. aresuspended from the cover 22 are also connected through the medium of thesaid bolt 20 as shown in Fig. 2. By this form of construction it will benoted that the ositive plates and connected hangers 21 are insulatedfrom the negative plates though all are connected togpther, and can beattached or removed as if at a single piece. A field wire 23 is attachedto a bolt 24. uniting the two hangers 21 andis thus obviously connectedto the opposite side of the batteryfrom what the wire 17 is attached.

In Fig. 1, we have shown in part' an eye 25 formed in the outer end ofthe yoke 13 and a separate screw 26 arranged therein and through the eye9 for the connection of he yoke, channel strip and hanger, instead ofdeflecting both ends of the as shown in Fig. 3.

While the hanger 7 is preferably formed in one piece as shown in Fig. 1,itmay be formed in several parts as shown in Fig. 3,

yoke down,

.and the sides thereof made adjustable with eral parts of the framesnugly against the edge of the negative plates in a way to rigidlysupport the same, yet leave the sides exposed for action, after thisthe'insula-ting blocks, the positive plates and the hangers 21, would beassembled in their respective orders and secured in place through the me'dium of the bolt 20 before mentioned.

' Having thus described our invention What we claim and desire to secureby Letters Patout is 1. An electrode support for batteries, comprisingin part, a top cross yoke, a sheet metal hanger including sides toengage the edges of the electrode and having a serrated i =edge toengagethe opposite faces of the negative plate, and means for securingthe hanger and yoke together.

2. An electrode support for batteries, comincluding a bottom and sideprising a frame including in part a top cross yoke havingits endsdisposed downward, a sheet metal hanger to engage an electrode andattached to the ends of the said yoke and having its edges serrated andbent over upon the face of the electrode.

3. An electrode support for batteries, comprising in part a top crossyoke, a hanger ortions adjustably connected together said side por tionshaving eyes in their upper ends, and means for securing the yoke andeyes togethen at. In an electrode support for batteries, the combinationof a sheet metal hanger adapted to engage the edges of an electrode andhaving serrated edge portions to overlap the opposite faces of theelectrode, means for securing the said hanger against the edges of saidelectrode and means for supporting the Whole from the cover of'a ar.

5. An electrode support for batteries, comprising in part, a top crossyoke, a sheet metal hanger having a serrated edge to engage the edgeportion of a negative electrode, and means for securing .the hanger andyoke together.
